The snow phenomenon is a marvel for those of us from the tropics, where we hardly experience snowfall. The first time I saw snow I was awestruck. Few people can fathom the wonders of snow.
Now, snow, I came to know, is a "union" of many small droplets called snowflakes. Singly, they even melt in your palm. In a "union", they can be as hard as a rock. And that is when they are most useful.
